What is the slope of the line that is represented by the values in the table above?
Answers
Answer:
1.5
Step-by-step explanation:
Given the pair of points on the table.
Now the formula for slope, [tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
To calculate the slope we only require two pair of points.
Let us take: [tex](x_1, y_1)=(-5,0)$ and (x_2, y_2)=(-3,3)[/tex]
[tex]m=\dfrac{3-0}{-3-(-5)}\\=\dfrac{3}{-3+5}\\=\dfrac{3}{2}\\m=1.5[/tex]
The slope of the linear function represented by the values in the table is 1.5.
Note: You can use any two set of values. The result will be the same.
what is the slope of the line that contains the points (-2,8) and (-2,1)
Answers
Answer:
0
Step-by-step explanation:
because -2 does not change
Answer:
Undefined
Step-by-step explanation:
To find the slope, you need the formula, y₂-y₁ divided by x₂-x₁.
That is 1-8 divided by -2-(-2), or -7 divided by 0.
Anything divided by 0 is undefined, so the answer is undefined.

Which function is the inverse of function f?
f(x)=9x^2–12
Answers
Answer: D
Step-by-step explanation:
If the equation is f(x) = 9x^2 -12, you can solve for the inverse by switching the x and y like this.
x = 9y^2-12.
Then you solve for y.
x = 9y^2-12.
x+12=9y^2
y^2=(x+12)/9
y=sqrt((x+12)/9)
y=sqrt((x+12))/3 which is D

Answers
Answer:
Step-by-step explanation:
A) Cost of canvas = $ x
Cost of 4 canvases = 4 *x = 4x
Money left over after buying 4 canvases = $2.20
Equation: 25 - 4x = 2.2
Solution: Subtract 25 from both sides
-4x = 2.2 - 25
-4x = - 22.8
Divide both sides by (-4)
-4x/-4 = -22.8/-4
x = 5.7
B) Money in Molly's account= x
4 times of Molly's account = 4x
Equation: 4x - 2.2 = 25
Solution: 4x = 25 +2.2
4x = 27.2
x = 27.2/4
x = 6.8

Quadratic Equations! Yes!
Step-by-step explanation:
Now, there are three methods to solving this:
1.Quadratic Formula
2.Factoring
3. Completing the square
Now, Based on the answers, I think it would be better if we used Quadratic Formula, as you cannot get the answer easily with factoring, and I'm a bit rusty on completing the square.
So, Quadratic Formula! To solve it using this method, we have to find x using this: [tex]x=\frac{-b+-\sqrt{b^{2} -4ac} }{2a}[/tex](the +- before the square root means it could be both positive or negative)
Where a, b are coefficients and c is a term(in a quadratic equation form: [tex]ax^{2} +bx+c=0[/tex])
So, we just have to input the stuff from our equation into the formula!
[tex]x=\frac{-4+-\sqrt{32} }{2}[/tex]
Now, we can simplify the square root of 32 into 4 times the square root of 2
[tex]x=\frac{-4+-4\sqrt{2} }{2}[/tex]
And, we can divide 2 from it all!
[tex]x=-2+-2\sqrt{2}[/tex]
So, there you have it! The Answer is C, or 3.
Hope this helps!

Answers
Answer:
The equation of the line in slope-intercept form is:
[tex]y=-\frac{3}{7} x+3\\[/tex]
In one of the many possible standard forms:
[tex]3\,x+7\,y=21[/tex]
Step-by-step explanation:
First calculate the slope of the segment that joins these two points: (0, 3) and (7,0):
[tex]slope=\frac{y_2-y_1}{x_2-x_1}= \frac{0-3}{7-0}=-\frac{3}{7}[/tex]
Now, knowing that the y-intercept is (0, 3) [point on the y-axis (for x=0) where the line crosses], Then the equation of the line in slope-intercept form is:
[tex]y=m\,x+b\\y=-\frac{3}{7} x+3[/tex]
And now, if you want to write the equation eliminating fractions, we can multiply both sides by "7":
[tex]y=-\frac{3}{7} x+3\\7\,y=-3\,x+21\\3\,x+7\,y=21[/tex]

Find the diagonale of the base.
Answers
Answer: 8.94
Step-by-step explanation:
By common logic, you can say that l=8, w=4 and h=2.
The diagonal of the base can be found by using Pythagorean Theorem.
Pythagorean Theorem: a²+b²=c²
Since we know the a and b of the base, we can find c, the diagonal.
a and b is the l and w. We can use the equation to find c.
8²+4²=c²
64+16=c²
80=c²
c=√80
c≈8.94
The diagonal is approximately 8.94

Can someone help me find the slope , y-intercept ,and equation pls help it’s my finals
Answers
Answer:
slope: -3
y-intercept: -5
equation: y = -3x - 5
Step-by-step explanation:
The formula for slope is:
(y2 - y1)/(x2 - x1)
Let's use these coordinates:
(-1, -2)
(0, -5)
x1 = -1
x2 = 0
y1 = -2
y2 = -5
Substitute into the formula:
(y2 - y1)/(x2 - x1)
(-5 + 2)/(0 + 1)
Solve:
(-5 + 2)/(0 + 1)
-3/1
= -3
slope = -3
The y-intercept is when the x coordinate is 0.
Looking at the table, we see the coordinate (0, -5).
The y-coordinate is -5.
This means that the y-intercept is -5
y-intercept = -5
Slope-intercept form:
y = mx + b
where m is the slope and b is the y-intercept
m = -3
b = -5
Substitute:
y = mx + b
y = -3x - 5
